SPL subwoofer custom Neo 12 will take 5000 RMS this sub is no joke the motor alone cost more than my asking price (see last 3 pics for similar subs same motor) asking $275 which is really cheap this sub has zero time on fresh coil brand new soft parts carbon dust cap hi-roll surround it used to be an 18 and took 9k rms in a competition converted to a 12 with a fresh rebuild ready to break in and push some air this sub is loud and will be a beast
